* Boot: switch to DFU routines. Implements #132 part 1 of 2. * Boot: boot to DFU shortcut, hard reset USB on each boot. Implements #132 part 2 of 2. * Deploy scripts: fix path for deploy dfu. * Bootloader: initial version. Target_f2: rebase, update deployment scripts. * Bootloader: cleanup, refactor switch2 proc. Readme,wiki: document bootloader. * Wiki: deploy symlinks as files, bootloader info. * Target_f2: valid flash size in linker script. * Github CI: bootloader build and artifacts. * Bootloader: rename platforms to targets. * Bootloader: change dfu/os colors. * disable set -e * lint code * add bootloader testing page Co-authored-by: Aleksandr Kutuzov <aku@plooks.com> Co-authored-by: aanper <mail@s3f.ru>
